LOUIS, MISSOURI STEH-ILIEAFSLZE This invention relates to new and useful improvements in surgical liquid dispensers, theprimary objects of the invention being to provide a liquid dispenser which can be operated to dispense a proper amount of liquid without requiring manual operation so that the users hands will not become con- 1 taminated.

Further objects of the invention are to provide a surgical liquid dispenser which is i of simple consiruction whereby danger of the mechanism getting out of order is reduced to minimum and can be easily operated.

Other objects of the invention are to provide a surgical liquid container which is detachably mounted. in position so that it may .be readily disassembled from the support and its operating mechanism for sterilizing Din . purposes.

for actuating said valve means, said mechanism beinga'dapted to be actuated by pressure applied bythe leg of thenser.

With these and other objects in view, my invention consists in. certainnovel features of construction and arrangement of parts, hereinafter more; fully describedand claimed and illustrated in the accompanying drawings, in which- Figure 1 isa sideelevational'view. of. the liquid dispenser showing the latter mounted on its support and connected to theactuating mechanism.

The surgical liquid dispenser can be advantageously used for dispensing various liquids used in doctors and dentists olilces, operating rooms, hospitals, and the like. Such liquids may be alcohol, liquid dentifrice, antiseptic solutions, liquid soap, and the like. I

Referring by numerals to the accompany ing drawings, 10 indicatesa support which detachably carries a liquid container 11. The container which .is preferably of cylindrical shape has its upper end closedby a removable cover12. The lower end of the container terminates in an extension 14 having a lip portion 15 in which is formed a discharge opening 16. Extension let is provided with atapered bore 17 opening into the interior of the container and revolubly seated in said bore is a tapered valve 18 having formed in its bodyportion a transversely disposed passageway 19, the upper end of which is adapted to communicate with an inlet opening 20 formed in the bottom of the container as shown iniFigure 7. The lower end of the passageway is. adapted to communicate with the discharge opening 16.

Extending upwardly from the bottom of the container 11 is a lug 11 in which is journaled a horizontally disposed rock shaftv 21. A beveled gear 22 is fixed to said shaft and meshing with said gear is a beveled gear 2a which is fixed to an upwardly projecting reduced extension 18 of valve 18. This on tension has a bearing in the horizontally disposedportion of a U-shaped bracket 25, the parallel portions .of which are upwardly presented and are loosely carried by roclr shaft '21,;thereby serving-as a support for said valve 18. Thus when rock shaft 21 is actuated valve 18 is caused to turn on its axis and position the passageway 19 either in communication with intake opening 20 or with the discharge opening 16. One end of shaft 21 extends outwardly from container 11 through a suitable packing gland 26 and has mounted thereon a rock arm 27. The latter is provided in its end with a slot 28 for receiving a horizontally disposed pin 29 which latter projects outwardly from support 10.

This support is preferably box-shape and comprises a wall plate 30 which is adapted to be secured to a wall A and a box-shaped cover 31 removably secured to wall plate 30 preferably by means of screws 32. The wall plate 30 is secured to the Wall in any suitable manner, such as fastening means 34. This wall plate is provided with forwardly and horizontally projecting bosses 35 which are threaded for the reception of screws 32 as shown in Figure 6. A horizontally disposed stud 36 extends inwardly from cover plate 31 and forms a support for a segment 37 which is mounted in support 10 for rocking movement. Pin 29 is secured to said segment and extends outwardly from cover 31 throughan arcuate slot 38. Stud 36 is substantially in axial alignment with rock shaft 21- so that pin 29 and arm 27 operate about a commoncenter.

A coil spring 39 is disposed in support 10 and has one end stationarily anchored as at 40 while the opposite end of said spring is connected'to said segment and tends to hold it in the position indicated in Figure 3. Segment 37 is actuated about the axis of stud 36 and against the infiuenceof spring 39 by means of a cable 41, one end of which is fixed to said segment at a point disposed opposite to the point of attachment of spring 39 with said segment. Said cable passes over the segment and extends downwardly from the support 10 through an aperture formed in cover 31 and has its lower end connected to a treadle or other actuating member 42 which is disposed a suitable distance below the container so that it may be conveniently operated by the user without the necessity of manual operation. Where a treadle is used, the latter is preferably'pivotally mounted on the floor as indicated at 44. Cable 41 passes over a sheave 45 which latter is fixed to the wall a suitable distance below the. soap dispenser.

The container 11 is detachably mounted on support 10 by means of horizontally and rearwardly projecting tubular extensions 46 which are formed integral with the lower end of said container and are adapted to be a placed over horizontally and forwardly projecting pins 47, which latter are secured to cover 31. Suitable locking means such as screws 48 are arranged on tubular extensions 46 and are adapted to engage pins 47 and lock said extensions in. position thereon.

Thus the container may be readily detached from its support for cleaning and sterilizing purposes, the slot and pin connection between segment 37 and arm 27 being readily disengageable from each other without necessitating adjustment of any of the parts.

The front wall of the container is provided in its lower end with an extension 49 having a window 50 thereby providing visual means for ascertaining the low level of the liquid contained therein.

Normally the valve operating mechanism occupies the position shown in Figures 3 and 4 and the valve occupies the position shown in Figures 7 and 8. When in this position passageway 19 is filled with the liquid but is sealed against discharge by virtue of the fact that the intake opening 20 is disposed at an angle to the discharge opening 16. Vhen segment 37 is actuated by means of cable 41, pin 29 is moved to the opposite side of the axis of the segment, thereby actuating rock arm 27 and imparting to shaft 21 rock motion. This motion is transmitted through gears 22 and 24 to valve 18 which is caused u to partly rotate and bring the passageway 19 filled with the liquid in register with discharge opening 16 and out of communication with intake opening'20. In this manner the liquid contained in passageway 19 is discharged through opening 16.

Where the treadle is released, the segment 27 is caused by the influence of spring 39 to move to its normal or home position, thereby partly rotating valve 18 in reverse direction and bringing the passage 19 thereof in com munication with intake opening 20 and out of register with discharge opening 16, thereby refilling said passageway for another op eration.

The container as well as all of the parts arranged therein are preferably made of non-corroding metal so that the container can be maintained at all times in sterile condition. No lubricant is necessary for the mechanism in the container as the liquid provides the necessary lubricating qualities.

In the modified form shown in Figure 11, the box-shaped housing 51 is arranged in a recess 52 formed in wall B flush with the face thereof and a cover 53 is detachably secured to said box-shaped body by means of screws 54. This form of housing is particularly adapted for use in new buildings wherein such housing can be built into the wall.

As the actuating mechanism is so arranged as to enable the user to operate the dispenser without the necessity of manual operation, it will be readily understood that not only the hands of the user remain in sterile condition but no assistance is required by the user to dispense the liquid. For these reasons this dispenser is especially adapted for use as a liquid soap dispenser for use in op erating rooms.

While we have shown and described the preferred form of our invention, it is obvious that various changes in the construction and arrangement of parts of our improved surgical liquid dispenser can be made and substituted for those herein shown and described Without departing from the spirit of our i11- vention.
